So I am trying to install V4A on a Samsung Tab 2 10.1 wifi running Lineage. However, i am unable to get it work appropriately. I've installed busy box and drivers, but can't find the lines that need to be changed. Any idea what I'm doing wrong?

Hey guys I was following the steps on how to install it and couldn't find the lines in the build.prop so I skipped it I did every step right but every time I install the driver and reboot when I first open it it shows the same message of the driver installation. Any suggestions on what I should do to make it work?
